IMX537 video problem under WINCE7 BSP

Branched to a new discussion

  We have a IMX537 board with a ADV7180BSTZ chip. The WINCE7 BSP has been successfully installed, everything goes well except the video function. We found:

 

  1, When CSI0 mode is set to "interlaced", there is no video output, also no IDMAC_EOF_0 interrupt is triggered.

  2, When CSI0 mode is set to "progressive", the images flap upward and unstable.

  3, When CSIO mode is set to "Gated Clock", the images are horizental mirrored.

  the following list is the setting of CSI0 registers:

        PID:00400002 TID:04D2004A Address d5290040  00000000 00000000 00000000 00000000

  Same video chip has been tested on the IMX357 board under WINCE6 environment without any problem.

 

  For this, any one with any luck in IMX537?

 

  BTW, could anyone explain the CSIO CCIR Code Register 1 ( IPU_CSI0_CCIR_CODE_1 ) to me? there is no detail explanation in the manual, such as the fields of:

       CSI0_STRT_FLD0_ACTV

       CSI0_END_FLD0_ACTV

       CSI0_STRT_FLD0_BLNK_2ND

       CSI0_END_FLD0_BLNK_2ND

       CSI0_STRT_FLD0_BLNK_1ST

       CSI0_END_FLD0_BLNK_1ST
